To all wkmit it may concern:

Be it known that I, Cmnms Scanner-ins, a citizen of the United States, residing at St. Louis in-the county of St. Louis and State of Missouri, have invented-new-and useful Improvementsin Rims, of which the following is aspecification. V

This invention relates to demountable tire carrying rims, and has for its chief object, the provision of a rim which is so constructed as to permit the application of atire thereto, or its removal therefrom without stretching the tire in any way whatsoever,

and without theuse of tools'generally used for this purpose. 7

More specifically stated, the invention provides a tire carrying rim' made up of inner and outer sections associated in a manner which permitthe sections to be easily separated for the association with or the removal therefrom of the tire, and said sections when connected together being capable of being readily placed upon the felly of the wheel and conveniently secured thereto.

The nature and advantages of the invention will be readily understood when the following detailed description is read in connection with the accompan ing drawings, the invention residing in t e-oonstruction, combination and arrangement of parts as claimed.

In the drawings forming part of this a? plication, like numeralsofreference' in cate similar parts in the several views, and wherein: p

Figure 1 is an elevation of a demountable rim constructed in accordance with my invention, and having a pneumatic tire associated therewith. Figure 2 is a transverse sectional view of the same.- Figure 3 is a perspective of one of the rim sections and igures 4 and 5 are perspectives of coacting rim sections. used in conjunction with the rim section disclosed in Figure 3.

Referring to the drawings in detail, A indicates a vehicle wheel provided with the usual felly band or false rim 10, which is secured to the felly of the wheel in any suitable manner. This rim is provided with depressions 11 which accommodate the plates 13 from which the threaded extensions 14 project. The body of each plate 13 is fitted in one of said depressions 11. Each plate is-secured to the elly band by afastening element 16. Manifest? the threaded extensions 14 project beyon one side.- of the band and are utilized to hold the demount able rimpositioned upon the wheel in .a manner to be hereinafter described.

17 and an outer section 18, and neither of these sectionsfis split as is the usual. tirecarrying rim. The outer section is slightly larger in diameter to slip over the inner sectiomimd the peripheral flange ofthe outer sc'tion 1s also slightly wider than isthe. oorrespfindmg. flange of the inner section;

The latter: mentioned flange of the inner} sectionfns indicated at 19 and vcarries ,a log "20 which is received by a slot 21 in a peripheral flange 22 of the outer section, the lug serving. to hold the valve stem 23 prop-- e rly positioned in the slot. The outer sec-- tion is further formed with an annular flange 24 which is arranged at a right angle to the peripheral flange 22 and the flange 24 j is provlde opposed openings 25 to receive the threaded BXlZGIISlOhS 14: wluch project from'the fellyband 10. The outer side of this flange 24 89 is one of these lugs 26 for each extension 14,

and each lug is provided with an opening which coincides withthe adjacent opening 25 above referred to.

When the rim in its entirety is positioned upon' the-wheel, the extensions 14 of the felly band project through the openings and lugs are then associated wit nuts 27 which bear against said lugs and old the rim in position upon the wheel. The inner surface of the peripheral flange 22 is provided with guides 28 to accommodate the plates 13 which are associated with the folly band or rim 10, and each guide extends beyond the opposite sides of one of the openings 25, and is substantially of U-shape formation in cross section. By reason of these guides the assoeiation of the rim sections is materially facilitated.

Carried by the inner section 17 of the rim and arranged at diametrically opposed points, is a pair of threaded bolts or the like 29 which are adapted to pass through the openings 30 formed in the flange 24 of the outer rim section, these bolts being equipped with nuts 31 to hold the rim sec- 1 tions fixed relatively when associated.

These are the onlytwo points at which the The rim proper includes an inner section 60 with a plurality of diametrically course, to-the separation of the rim from the wheel, whereupon the rim sections can be separated for the phrase mentioned. The tire is first arranged a.

18, vandithenthe inner section is slipped ve the outer section within the outer section in .a manner which permits the tire to be mounted upon the rim, without either -stretching the tn'e or necessitating the use of the tire rim tools'of'well known constructiom After the sections have been associated, "the rim together with the tire can be easily slipped upon the wheel,

the extensions l l'thereof passing through the openings 25 above referred to.

While it is believed that from the foregoing description, the nature and advantages of the invention will be readily ap'pagent, I
